Nao Omori in Ichi the Killer (2001). In Takashi Miike's Ichi the Killer, the famed Manga series from Hideo Yamamoto is brought to life, particularly by Nao Omori, who scarily embodies the titular assassin. Manipulated by the devious Jijii (Shinya Tsukamoto), Ichi is harmless until he becomes enraged, which leads to homicidal—and crazily sexual—tendecies. Ichi is implanted with painful memories and used as a killing machine, and from there, the death toll in this grizzly thriller keeps climbing.
